""Roger Bacon's Letter: Concerning The Marvelous Power Of Art And Nature And The Nullity Of Magic"" is a book written by Roger Bacon, a medieval philosopher and scientist. The book is a letter addressed to Pope Clement IV, in which Bacon discusses the power of art and nature, as well as the invalidity of magic. Bacon argues that the power of art and nature is far greater than that of magic, and that magic is nothing more than superstition and deception. He also discusses the importance of scientific inquiry and experimentation in understanding the natural world. The book provides insight into Bacon's philosophical and scientific views, as well as his religious beliefs, and is a valuable historical document for understanding medieval thought.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
